LGCKING DEVEGE FOR TIRE-RETAINING ATTACHMENTS.

Specification of Letters Patent.

Patented J an. 1 5, 1907.

Original application filed April 28,1906, Serial No. 314.230. Dividedand this application filed July 14, 1906. flerial No. 326.232.

To all whom it may concern.-

Be it known thatl, Brennan S. BRYANT, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented certain new and use ful Improvements in Looking Devicesfor Tirc-Retaining Attachments, of which the following is aspecification.

My invention relates to improvements in a locking device fortire-retaining attachments, especially of the construction shown in mypending application, Serial No. 270,218, and comprises 1m roved meansfor preventing the elastic loc ring-ring from being unseated by severeusage.

It consists, essentially, of a clasp member ada ted to be positionedupon a lug extending slow the rim-body to engage the locking-ring and tohold the same securely in its normal position against the tire-retainingring.

The device herein shown'is an improved form of the device shown in mypendlng application, Serial No. 314,230, of whichthis application is adivision.

The accomplishment of the foregoing purposes is achieved by theconstruction hercin after described and claimed, a preferred embodimentof which is shown in the drawings,

Figure 1 is a side view of a portion of the circle of the rim-body,showing the locking device in place. Fig. 2 is a cross-section. of therim-body with the tire-retaining flanges and the locking-ring andlocking device in place. Fig. 3 is a side View of a portion of therim-body with arts in place, the clasp member partly bro (en away to exose the lug. Fig. i is a top view of the on s of the looking-ring Fig. 5is a side view of the ends of the locking-ring. Fig. 6 is a modifledform. of the clasp member adapted to be used with the locking-ring,having its ends cut away as-shown in Fig. 7. Fig. 7 is a modification ofthe locking-ring. Fig. 8 is a vertical section through the rim, showingthe clasp member illustrated in Fig. 6 in place.

Referring to the accompanying drawings, 1 is the rimbody, adapted foruse upon a vehicle-wheel constructed in a well-known manner.

2 is the outwardly-turned flange upo'n'the inner edge of the rim-body.

3 is the inwardly-turned flange upon the outer edge of the rim-body.

4 is a tire-retaining flange which is adapted to he slipped over therim-body firom the outer edge thereof and positioned against body onaccount of the pressure of the inflated tire by contacting with thelockingring 6, which engages the tire-retaining flange 5 at 7. Flange 5is prevented from moving inwardly by the inflated tire, so that when thetire and flanges have been posi tioned and the tire inflated the flange5 re securely held in position against the tire by the locking-ring 6.The'locking-ring 6 is split, as shown at 8, and is ada ted to bepositioned by being sprung inwar ly and then permitted to expand intoposition u on the downturned flange 3, where it is he d against outwardmovement by the engagement of the inner flange 9 with the downturnedflange 3. When in position, the locking-ring 6, which is U-shaped incross-section, embraces the downturned flange 3 and is held thereon byits own expansion, and when on account of the outward pressure of theinflated tire the outer arm 10 of the locking-ring 6 isengaged by thetire-retaining flange 5 the locking-. ring is held from being forced offthe rim-body laterally by the engagement of the flange 9 with flange -3.

It is to be understood that the mani ulation of the tire-retainingdevices herein s own is as follows: The retaining flange 4 is placedupon the rim-body, over the outer edge thereof, and is moved laterallyacross the face of the rim-body until it engages the flange 2 and isheld thereby against pressure adapted to force it off the rim-body.Flange 4 may be brazed or otherwise secured to the rim-body or it may beleft detachable. The tire is next positioned upon the rinvbody,

over the outer edge thereof, and the outer mg-ring 6, which in turn willcause flange or arm 9 on said locking-ring to engage against the innerface of the inwardly-turned flange 3 on the outer edge of the rim-b4-dy.

Ordinarily the device thus far described would be sufficient formaintaining a tire permanently in position for use upon the rim-body;but the jarring and jolting due to uneven roadways require additionaldevices for the purpose of securing the locking-ring firmly in place,and 1 hr e therefore provided a locking device which I will now proceedto describe.

My device comprises, essentially, a clasp member 11, formed to beessentially U- shaped in cross-section, the outer arm or flange 12 beingpreferably longer than the inner arm or flange 13. Through the lower orbody portion is provided an opening 14. On the under side of therim-body, in proximity to the inwardly-turned flange 3 thereof, Iprovide a lug or bolt 15, extending downwardly from the under 'facethereof. Preferably a hole is drilled through the rimbody, and the bolthaving a flat head is inserted through this opening from the upper faceof the rim-body, and the head thereof is made flush with the upper face,and the bolt is secured in place, preferably, by brazing. At its lower,end lug 15 is threaded to receive a nut 16. The locking-ring 6 near itsends has its inner flange 9 cut away, as shown at 17 and 18, and whenthe locking-ring is positioned the ends shown at 17 and 18 abut againstthe lug, and are thereb held against circumferential movement. T e outerflange 10 of the locking-ring 6 has its ends out slantingly, so thatthey will overla as is apparent in Fig. 3 and Fig. 5. W on the parts areproperl positioned on the face of the'rim-body an the locking-ring hasbeen sprung into place, the clas member 11 is positioned upon the lug,so that the flange 13 engages the lug upon its inner side, and

. flange 12 engages the outer face 10 of the lockm -ring at the junctionof the ends thereo and when the nut 16 is positioned and turned tightlinto engagement with the clasp member t e latter is caused to embracethe locking-ring and hold the same securely against displacement.

- In Fig. 6 is shown a modified form of the clasp member, (indicated at27,) which has its longer flange 28 of triangular shape and adapted whenpositioned upon the lug to be between the ends'of the locking-ring,which in this construction are made divergent, as-

shown in Fi 7. This latter form of clasp member is s own locked in placein Fig. It is understood that the clasp member Wlll be positioned on thelug in the same manner as in Fi 2; but when the nut is turned against tie clasp member the latter will be driven between the ends 19 and 20 andthe same will be forced apart and squeezed into secure engagement withthe tlre-retaining flange and rim-body. The latter construc-- tion isneater in its appearance and is equally effective.

The device described herein is simple in its construction and effectivein its operation and by its use any tendency of a split selfexpansivelocking-ring to be unseated from its operative engagement is completelyobviated.

What I claim as new, and desire to secure by Letters Patent, is

1. A locking device for tire-retaining attachments comprising arim-body, a downturned flange u on the outer ed e thereof, a lugdepending om said rim-bo y, a broken locking-ring having inner and outerradial flanges, the lnner flange being cutaway near the ends thereofwhereby said locking-ring is positioned against said lug to preventcircumferential movement, a member adapted to be slipped upon said lugto embrace said locking-ring, and means for securing said member inplace whereby the parts are securely locked in position. I

2. A locking device for tire-retaining attachments comprising arim-body, a downturned flange u on'the outer, edge thereof, a lugdepending om said rimtbo y, locking-ring adapted to be positioned uponsaid rim-body by self-expansion outwar ly, and abuttingcircumferentially a a broken XI ainst said lug, a clasp member adaptedto be slipped 7 upon said lug to engage said lockin -r1ng, and means forsecuring said clasp mem er 1n place.

3. A locking device for tire-retaining attachments comprising arim-body, a down- IIO turned flange upon the outer ed e thereof, a

lug depending m said rim-b0 locking-ring ada ted to be positloned uponsaid downturns flange by self-expansion outwardly, the ends of saidlocking-ring be' ing beveled divergently from the uppzr sigie thereof, aclasp member adapted to tioned u on said lug to engage the en 5, of said'ingrin and means for securing y, a'brokenv said. clasp mem er inpla'ce, whereby the parts are securely locked in position. i
